Hello, I'm a new member that joined explicitly with the hope that someone in this awesome community might be able to help me out with an issue that I ran into last night. I developed a roll of Delta 400 from my Pentax 67 last night, and was disappointed to see a weird band/line on the left hand side of the frame in the best shot from the roll. Does anybody here have idea what this is, and if there is any way to fix it? For what it's worth, the band appears to be on the emulsion side, and not on the glossy side of the film (I already tried wiping it off on the glossy side to see if it was a mineral deposit and no luck). I suspect the issue isn't uneven development or insufficient agitation as I used rotary processing for this for both the development and fixing stages. I also don't think it's a mineral deposit because I use photo flo and a lot of distilled water for the final rinses before hanging (I rinse twice with distilled water before the photo flo step, when I again use distilled water). My best guess is that this is maybe the result of the negative drying unevenly and in such a way that that band appeared? I hang my negatives up to dry, and I think this negative was at the bottom of the roll, so any leftover water could have accumulated in this general area as the water droplets gradually moved down due to gravity. Will soaking and or re-washing the negative in the hope that re-softening then drying the emulsion again remove the line? I want to use this negative for darkroom prints, hence my desire to fix the negative if possible... Thanks in advance for anybody's help!
